APPARATUS FOR TREATING OIL.

Applicationflled ti'ebruary 16, 1925. Serial No. 9,676.

To (112 whom it may concern: I

Be it known that I, ZENO E. DAUonnmL,

a. citizen of the United States, residing at Corsicana, in the county ofNavarro. and

State of Texas, have invented a new and useful Apparatus for TreatingOil, of which the following is a specification.

The invention relates to a new and improved apparatus for treating oilwith which are mixed water and gas. Considerable difficulty is usuallyexperienced in affecting the complete, efiicient separation of theseingredients and it is an object of the present invention to provide acompact and simple apparatus which, by the use of steam, will quicklyseparate the mixture.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel steps inthe method and in certain details of construction of the apparatus whichwill be hereinafter more fully described and pointed out in the claims,it being understood that changes may be made without departing from thespirit of the invention as claimed. 1 p

In the accompanying drawing which is a section through the apparatusused, one form of mec anism for carrying out the method has beendisclosed.

Referring to the drawing by characters of reference 1 designates thetank of any suitable proportions having an oil outlet pipe 2 extendingfrom the top portion thereof. An outlet pipe or syphon 3 for carryingoff water and other heavy fluids, communicates with the bottom portionof the tank as shown at 4 and also with an intermediate portion of thetank shown at 5, both of these points of communication being below thelevel of the water to be drawn from the tank.

-The outlet 5 is preferably downturned as shown.

The top of the tank may be conical as shown at 6 and is closed, this topsupport- .inga drum"7 constituting a gas separator. The drum has itsbottom downwardly to an outlet pipe 8- which exortion tapered tendsdownwardly within the central portion of the tank 1 and is rovided witha desired number of radial yextended outlet pipes 9 each of which hasits fr'ee end up turned within the tank 1 as shown at 10. In the 'outletportion of each of the branch pipes 9' is a nozzle 11 discharging towardthe outlet and connected to a pi e 12 which 1s supported below the freeen portion of the branch pipe and has an inlet 13 in the.

In .using this apparatus the mixture of oil, water and gas is conductedto the drum 7 by the pipes Band 17 and discharged downwardly. As themixture is delivered into the drum the gases will be separated therefromand will rise and flow outwardly into pipe 16. The water and oilmixture, however, will flow downwardly within pipe 8 and be deliveredradially through pipes 9' and thence upwardl into the tank at the outlet10. Steam is irected into the respective pipes 12 and will be deliveredin a jet toward each outlet 10. The steam will act to break up themixture of oil and Water as it flows toward the outlet 10, the oilrising to a higher level than the Water within the tank 1. It will benoted that the steam will flow past the inlet 13. Thus a portion of thetank will be kept in circulation, this Water entering the inlet 13,flowing along pipe 12 with the steam, and being delivered with the steamfrom the nozzle 11. By thus keeping the water in circulation thetendency of recombining with the oil is eliminated and the separation ismore rapidly and efliciently efl'ected than would otherwise be possible.Oil is withdrawn through the pipe 2 at will while the water level can bemaintained where desired by drawing ofi' quantities through either orboth of the outlets 4 and 5.

What is claimed is 1. Apparatus of the class described including a tankhaving an oil outlet and-a water outlet at diiferent levelsrespectively, a pipe opening into the lower portlon of the tank, fordelivering a mixture of oil and water to the tank, a delivering pipeextending from said first named pipe having an outlet opening into thetank, a steam nozzle within the outlet pipe, a steam .pipe communicatingan 011 outlet adjacent the top with the nozzle, and a water inlet pipeopening into the steam pipe for directing water into said steam pipefrom the interior of the tank.

2. Apparatus for use in the separation of oil, water and gas, includinga tank having an oil outlet and a water outlet at difierent levels, aseparating drumhaving a gas outlet, means for delivering a mixture of011, water andgas into the drum to separate the gas from the mixture, apipe for conveying a mixture of oil and water from the drum into thelower portion of the tank, delivering pipes extending from the firstnamed pipe having outlets openmg mto the tank, asteam nozzle within eachof said delivering pipes, a steam pipe communicating with each nozzle,and a water inlet plpe opening into each steam pipe for directing waterinto said pipe from the interior of the tank.

3. Apparatus for use in the separation of oil, water and gas, includinga tank havin thereof an water outlet adjacent the bottom thereof, aseparating drum above the tank having a. gas outlet at the top thereof,means for delivering a mixture of oil, water and as into the drum toseparate the gas from t e mixture, a pipe extending from the drum to apoint within and close to the bottom of the tank,

radial delivering pipes extending from the bottom of said downwardlyextended pipe e z. E. DAUGHDRILL,
